Politico:  For Senators, Tax Questions Are Taxing:

Last week, Politico asked the offices of all 99 sitting senators to say who prepares their taxes, whether they or the Internal Revenue Service has ever discovered an error on returns they’ve filed, and whether they’ve ever had to pay back taxes.

Of the 56 senators who have responded to the survey, eight said that mistakes have been made on their tax returns, and six said they have paid back taxes. Thirty senators said that no mistakes have been discovered on their returns and that they’ve never paid back taxes — at least to the best of their recollection.

The offices of two senators — Jim Webb (D-Va.) and Bernie Sanders (I-Vt.) — told Politico that they would not answer the survey questions. The offices of Kyl and 42 other senators — 17 Republicans, 24 Democrats and Joseph I. Lieberman (I-Conn.) — failed to respond at all.
